标准作业评估与改进方法-泰科
4.PROCEDURES
4.1.
Form a core implementation team to lead the planning process and manage the implementation (refer to Standard Operating Procedure TEC-407-702).
4.2.
Determine required Takt time.
4.3.
Record all steps in the current process on the Time Observation Form (3767-1).
A.
Time observations are not a time study for setting rates.
B.
Time observations are a tool to map and document all elements of the process so waste can be identified and reduced or eliminated.
C.
Two-person teams are the recommended minimum for taking the time observations (one person serves as the timer and the other person serves as the recorder).
D.
Record accumulative times for several cycles of the operation.
E.
Calculate the individual task times after the observation is completed.
F.
Involve the worker in the time observation.
G.
Observe more than one cycle of the operation.
H.
Confirm the task sequence with the worker.
I.
Break down the tasks into the smallest measurable elements and combine the very small tasks.
J.
Take multiple time measurements depending on variability and length of cycle.
K.
The lowest repeated time is considered correct since it obviously had the least WASTE.
L.
Identify waste / variation
1.
Identify and reduce waste
